Flotation is the main method for recovering and reusing fine low-rank coal by taking
advantage of the difference in physicochemical properties of the mineral surface, but its …

Globally, low rank coals are responsible for about half of the world's total coal deposits.
However, these low rank coals present a high moisture content, which significantly impacts …

Microwave irradiation has gained widespread popularity in coal processing. However, the
effects of microwave parameters and coal properties on the heating behavior remain much …

Researches about mathematical modeling of electrohydrodynamic (EHD) drying are rare. In
this study, hot air combined with electrohydrodynamic (EHD) drying behavior of thin layer …

As hydraulic fracturing as a means to enhance coal bed methane was banned in some
countries due to possible negative environmental impacts, the microwave heating was …

The dried ammonium polyvanadate (APV) can be used to produce high-purity Vanadium
pentoxide (V 2 O 5) by calcination. Therefore, drying is a necessary process. The …

Dehydration is a necessary link for lignite upgrading, and evaporative dehydration is one of
the most effective dehydration technologies for lignite. Kinetics, as a fundamental …

In this study, the microscopic adsorption behaviors of two ionic surfactants, sodium dodecyl
sulfonate (SDS) and dodecyltrimethylammonium bromide (DTAB), on the lignite surface …

A new type of high-efficiency dust suppressant for mines was synthesised by graft
copolymerisation, with carboxymethyl chitosan serving as the matrix, and the microscopic …

The thin-layer drying characteristics of **meng lignite (XL) were investigated under
microwave irradiation, and mathematical modeling using thin-layer drying models from …
